Good day. I am playing clarinet for almost 20 years, and it is my first time studing seriously. After 1 month of constant 2-3 a day studing i noticed that my technic is not good concernig the fingers. It is impossible for me to play fast enough, and my forearms are in pain after studing. I suppose i am appling a lot of pressure on the clarinet so my fingers can't have the speed nessesary. What do you suggest i do in order to "lighten" my fingers and speed up my fingers???
